Third stage of implementing an out-of-line constant pool for Arm.  This CL adds
a ConstantPool field to Code objects and initializes the pp register on
function entry, and saves the pp register on the stack frame. The ConstantPool

7ac7a7ea99 Fix a race between concurrent recompilation and OSR. 
If concurrent recompilation finishes before OSR, then OSR replaces
the old optimized code without evicting it from the optimized code map.

New functions can get the old optimized code from the optimized code map,
but the old code could be already deoptimized.

2a4be7067c Refactor the compiling pipeline. 
Goals:
 - easier to read, more suitable identifiers.
 - better distinction between compiling optimized/unoptimized code
 - compiler does not install code on the function.
 - easier to add features (e.g. caching optimized code for osr).
 - remove unnecessary code.

79ad8bf2e0 Fix sporadic crash in the RequestInterruptTestWithNativeAccessor. 
The test was broken. V8 currently does not correctly lookup NativeDataProperty accessors attached to the PrototypeTemplate of FunctionTemplate (Issue 3066). As the result while(obj.shouldContinue) loop was immediately exiting and the test would terminate while RequestInterruptTestBase::InterruptThread would be still starting up. As the result later InterruptThread would try to access members of the test object which was destroyed.

The test was fixed:

- instead of attaching accessor to PrototypeTemplate we attach it to  InstanceTemplate;
- an assertion was added to verify that we completed the test successfully due to interruptor firing not due to sporadic loop termination due to some unrelated bug.

e654c88fab Remove flag track-allocation-sites. 
The flag has been on in the build for ~9 months, and we aren't likely to turn it off. The only customer of the flag is a set of tests that want to verify transitioning behavior in isolation. This CL removes the flag and updates those tests to get what they want without the flag.

e595dc0368 Revert "More API cleanup." 
This reverts r18383. The CL in itself is OK, we just have to wait until Chrome's commit queue lands the final corresponding change and re-land this CL. :-/

d54a4e6d40 More API cleanup. 
* Removed String::Empty, Number::New, Integer::New, Integer::NewFromUnsigned, FunctionTemplate::New and Object::New without Isolate* parameter.

* Removed Integer::New and Integer::NewUnsigned with weird argument order.

Chrome CLs matching this change are prepared, BTW.

e6ef64c590 [platform] Implement a worker pool 
We don't use the worker pool yet, however, there are tests. Yay. The
next step is to use the worker pool for parallel sweeping.

I've also started to move the platform related files into a sub
directory. The goal is to eventually build all the platform stuff as
a separate library which is used by d8 and cctest (and other embedders
that wish to use the default implementation) but not by chromium.

0dbbedc344 Fix number of parameters passed into PrepareCallCFunction in code age stubs 
In r16710 Additional parameter (Isolate) was added to parameter lists of some native functions called from the generated code. However, corresponding PrepareCallCFunction arguments changed only on i32. This CL updates other architectures to match actual value.

4b6ada0f55 Avoid SLOW_ASSERT when calling HeapGraphNode::GetChildrenCount 
It may occur that GetChildrenCount is called on the node which has no children and stored last in the internal nodes array. In that case HeapEntry::children_arr() would fail when taking address of the element at index children_index_ which is past the last element in the children's array.
